Microsoft today released Windows 10 Redstone 5 preview review build 17760 to Insiders in the fast ring. This is the second Insider release this week and comes on the heels of a week with tons of updates for all currently supported versions of Windows. There are no new features in this build but there are plenty of fixes, improvements, and no known issues. Here is a look at what you can expect in today’s build heading into the weekend.

Windows 10 Redstone 5 Build 17760

Here is the list of fixes, changes, and improvements for this latest build:

The build watermark at the lower right-hand corner of the desktop is no longer present in this build. This does not mean this is the final build as we are not done yet. We’re just now beginning the phase of checking in final code to prepare for the final release.

We fixed the issue causing apps that use .NET 4.7.1 to not work correctly in previous builds.

We fixed an issue resulting in rendering issues in certain types of PDFs in Microsoft Edge.

We fixed an issue that could cause a crash when using swipe to navigate back in Microsoft Edge.

We fixed an issue resulting in Microsoft Edge crashing after pressing F12 on certain webpages if certain extensions were enabled.

We fixed an issue resulting in the icons on Microsoft Edge error pages not being visible on localized builds.

We fixed an underflow in the Windows Security app that could result in the UI unexpectedly showing a very large number of threats had been found.

It’s also worth noting that, unlike most of the previous preview builds, Microsoft says there are currently no known issues to report. But, of course, if you do notice anything, the company encourages you to let them know via the Feedback Hub. Make sure to read the full release notes for all the details. If you are an Insider, let us know how this latest RS5 builds are (or aren’t) working on your test systems.
